1. First of all, I recommend the official manual of mplus, because it is officially published by mplus and is the most authoritative, and its content will be updated in time with the upgrade of mplus. The disadvantage is that some contents are brief and lack of in-depth explanation.

2. Secondly, I recommend Wang Mengcheng's "Latent Variable Modeling and mplus Application", which should be the first textbook dedicated to mplus operation in China. The content is detailed, involving many commonly used research and analysis methods, which is easy to understand.

3. Then recommend some books about statistical econometric research methods, and attach some operational statements of mplus, such as Wang Jichuan's Structural Equation Model: Method and Application, Qiu's Structural Equation Model Principle and Application, Luo Shengqiang's Research Method of Management Questionnaire, and the analysis of regulatory effect and intermediary effect.

4. There are always some relatively new analytical methods that are not involved in all kinds of textbooks. Related mplus sentences may need to be found in some professional journal papers, and many papers will attach mplus sentences at the end of the paper.
